Ambush victims' families visit Mexico massacre site

The family members stopped by the roadside to embrace one another as they remembered their relatives. One woman laid a wreath of flowers.

Three women and six children were ambushed in Sonora state on Monday, leading U.S. President Donald Trump to urge Mexico and the United States to "wage war" together on the drug cartels.

Authorities and relatives say the killings appeared to be the work of the Juarez and the Sinaloa cartels, which fight for control of lucrative drug routes that run through the sparsely populated mountainous areas into the United States.
